1. How much should I practice a day if I really want to make it big?
2. Is it possible to support myself entirely off of SC?
3. What would I do after I'm like 40 or something, what do I do then(since if I took a "normal" job career I would still have a job then, or something?)
4. Could I support a family off of this?(like nony and white ra, I'm unsure as to their situations)
5. If I really want to go pro, like try to support myself fully off of starcraft, would I join a team? Is that really my only choice nowadays is to get sponsored*? Furthermore*, should I plan moving to korea? I know this wouldn't happen for a long time, but I'm just trying to get my thoughts on paper now.
6. How many hours should I at least be putting in in starcraft now? Right now I would say I average 2-3 hours playing starcraft and like 4-5 watching streams/day9 or so forth. Some days I average more, such as weekends when I play for like 5 hours or something.
NOTE: These are all my personal opinions.
1. Practice hours needed to get better varies for each person. Some might say at least 6 hours up to 10 hours a day or more; taking into account that you want to be on the level of Nada or Boxer in the Brood War days. Now, people may argue that SC2 is a very different game mechanically as SC:BW, but that doesn't mean you don't need to put in the ridiculous amount of time to practice.
2. It IS possible for someone to support themselves entirely off of SC2 but not right away as you are probably hoping. My best example would be comparing Boxer to other SC2 pro-gamers. Currently, no one compares to Boxer when it comes to salary but players like Nestea, Fruitdealer and ITR are probably doing alright from their GSL winnings and some part of salary from the team. Now, that is the bright side of pro-gaming but you have to realize that only the VERY FEW can live off of this game like this.
Most pro-gamers are sponsored by the team but the salary aren't enough to live off of that a part-time job is a must in order to pursue their dream; which some can get by actively joining tournaments/cups of all levels.
3. It depends. That is a risk you must accept if you are to pursue this venture. There are some that ends up working for SC broadcasting companies and becomes broadcasters but once again, only a FEW will be lucky enough. The safest bet is what most pro-gamers are doing, which is to stay in school/have part time job while juggling tournaments and attending events. People like Day9, qxc, and Morrow are still in school and still can find time to become the top few relevant players in the scene.
4. No one is sure about their own situations aside from them and maybe their friends but I'm assuming that they get a good amount of financial support from their spouses aside from their salaries from their teams. Once again, I do not know their situations but I'm thinking this is the most logical explanation. So my answer would be it varies between people and it depends on what their/your financial situation is.
5. Stupid question. YOU HAVE TO JOIN A TEAM (unless you're Boxer in which the team joins you). How else will you get money? Will you shell it out yourself? Since you have to fully support yourself from pro-gaming, then you go where you think you win that said money. If you can consistently place high in every MLG events, then you can probably get by but the current chances of someone consistently placing 1st in every major event is fairly low. (i.e. MLG, GSL)
6. See Answer 1.
Conclusion: You are not ready to be the very best like no one ever was. You are very unsure of all this things you should already know by common sense. The harsh reality is that no one in their right mind go in to pro-gaming thinking they can fully support themselves solely by it right away. You must first become a good amateur gamer and then get recruited into a team/sponsor before even thinking you can fully support yourself. Nothing is impossible but what you are asking for is a clear-cut answer and the problem is, there is no such thing. You can be the biggest gamer there is but it takes a lot of dedication, talent, and drive to get you there. All of which you don't seem to currently have.
