I'm not saying you can't hit 10K this year(others have done that in their first year), but that's a lofty goal especially beginning at the penny tables(not saying that's a bad idea though).
I think you have set yourself an unrealistic target which is almost certain to affect you emotionally when you hit a bad patch.
I often wonder how much of the talk of downswings, variance, sustainability and generally what is reasonable is actually the voice of reason or if in reality it stems more from the speaker's dissatisfaction with their own results.

I think some of you are being too pessimistic. I started playing at the penny tables on Paradise and within that first year I had made over $10K. Grant it, a large portion of it was from MTTs, but the buy-ins for the MTTs were funded by playing ring games.

It's not just me and I don't think I am a particularly good player either. I could cite many players on FTR that started with a modest initial deposit and within a year had bankrolls of several thousand with numerous withdrawls made along the way. If you gave me $100 I know I could turn it into $10K within a year. You don't even have to be a very good player to start as long as you have a strong motivation to learn and improve. A year is a long time and the progression an improving player makes through the lower limits can/should be rapid. You can go from playing the penny tables to $10 NL to $25 NL in literally a matter of weeks.

The problem isn't people aiming too high and missing. It's too many people aiming low, hitting, and being pleased with the result. If anything, I think too many people set their goals too low. If you are disciplined, you or anyone else can make more than $10K in a year easily. If you're not disciplined then you're probably not going to reach a lower goal anyways. With no discipline I'd bet against you to make much more than even $100.

I'm assumming that you are disciplined (Are you? The vast majority of people playing poker are not.) and if you're not currently a good player then that you're willing to take the necessary steps to become one. If you meet those criteria then you're goal is definately doable even with such a small starting BR.

Like others have mentioned, I think it would be a good idea to establish other smaller goals on the road to achieving your ultimate one. If it was me, my first task would to earn enough to be bankrolled for $10 NL. My next goal would to be bankrolled for $25 NL, etc. If you want to make $10K you're going to have to make these steps along your way. If you keep making those steps then making $10K+ will take care of itself.

Aim high, if not higher. With motivation and discipline pretty much no goal is unreasonable. Without them though you're destined for failure.
