<prompt> Human: I recently moved up to San Francisco age 16 and am renting a room for 1250. Im currently doing occasional contract work, where I make about 800 a day. Im averaging 2-3 days a week, but can easily work all 7 if I needwant. Outside of rent, my expenses include transportation and food, which are looking like theyll be 300 and 400 this month, respectively.Given my financial situation, what can I do right now to put myself in the best possible financial situation in the future 5, 10, 25, 50 years down the line? Id like to open up a credit card and start putting small regular expenses on it to build up credit, but Ive been having trouble getting one issued because of my age.EDIT: I should have included more details, sorry about that. Im currently doing software consulting and am out of high school. Im not currently planning on going to college.  <response>: My immediate reaction is to say make sure you are paying your taxes if it isnt already being done, could be a shock at the end of the year!
