..... and if you do sort out a problem and the solution is free, let people know about it. Don't boast, just be all casual like. If you think your 1st job may involves sales - know your product inside out and backwards - obvious I know, but so many people just don't! I am responsible for the IT at a very small company and had to sell problems AND their solutions to those with the cash, to get the budget. Sales skills can help even when you're not selling. The very best in your endeavours.
