Out of every $1 you make save 35 cents then at the end of the year make a contribution to a 401k or your Roth IRA, then when you go to the account to get your taxes done show him the statement of your contribution to either of the savings. You can deduct your contribution of your taxes and you'll get it back in your refund.
Save all receipts because if you had to buy some thing for work you can claim that and get that and get that money back too.
