Speaking from a player who has his sole income from grinding 1/2 I have mixed emotions about it. This year I am making $17.60 an hour. Problem is that I have expenses that are crazy so its very very hard to ever get a chance to go to 2/5. My bankroll takes a hit almost every month. A large part of the reason it takes a hit is because I go to school fulltime.
OP, a lot of the people in this thread have given you good advice. Some people are for it, and others are against it. Coming from someone who plays for his income until I graduate univeristy, I can see both sides of the coin. If you ONLY play 1/2 as your sole source of income, the odds will be against you to ever move up. If you are a small winner though you will drown in the dust.
If you get the job part time at some place like subway, even if its 12 hours a week, you will have a much higher chance of succeding/making REAL money at 2/5. Let's face it, its going to be tough to move up stakes when you are grinding ur ass off at 1/2 because of living expenses. Working 12 hours a week even at $8/hour will keep you afloat in a downswing and keep gas in your tank. That way you dont have to take a lot of ur roll our for expenses, and being able to grow your roll will be way easier so you can move up to 2/5.
There is so so so much more than what goes beneath the surface when playing poker for a living. Here are some miscelaneous, random thoughts and tips that I will give to you in no specific order that you need to do to be successful:
1) Make sure you exercise. Purchase a gym membership
2) Post hands on 2p2, watch videos from Bart Hanson.
3) Skype hands with some of the 2p2ers on this site.
4) Make sure you get good rest.
5) Live a balanced life. Make sure you go out with friends.
6) Be a nit with expenses. Don't spend/splurge your winnings away.
7) Don't get too high on an upswing and low on a downswing.
8) never be results oriented
9) Be truley upset when you win a big pot and misplayed a hand/got lucky. Be mad when you win the pot but miss max value.
10) Be happy when you loose when you played the hand the right way. Be happy when villain sucks out on you and you loose your stack, so long as you played the hand the right way.
11) Leave the game asap when you are on your C game. This is the biggest hit to your br.
12) Walk away when you are steaming
13) Soak all the good information you learn like a spunge.
14) Always have a 4k+ bankroll. This way you never worry about not taking up a small edge that you need to take.
15) Eat Healthy. Subway isnt really healthy
