In gambling i set small realistic goals which is easy to actualize. I believe in taking small profit now and then than waiting for the big catch. While the ROI may not be much, it is better than waiting ages to hit the jackpot.
I lean more towards small progressive goals when I am building my poker bankroll. With every small target I hit with my bankroll, I am motivated and I don't get myself pressured over big numbers. What that approach does for me is that I am never under pressure to force actions when the cards aren't favouring me.
