Hi Sam
Firstly, you're never too old to begin learning magic. With some dedication, lots of practice and some judgement in what you spend you money on you'll find that you pick up the basics in not time at all. The rest is up to you.
I'll recommend that you spend some time looking through the different areas of this site and you'll learn lots about beginning, what to buy, where from etc.
I'm sure that many of the members will recommend that you get in contact with a local magic club or society. Most have different levels of membership so it's always worth making an enquiry or two. However, if they don't accept you to start with then don't be put off!
AS to what's on in your area, check out the Magic Week web site at
http://www.magicweek.co.uk for up to the minute news on what's happening (well nearly up to the minute).
Finally, you'll also find that many of us here also have full time jobs but haven't let that put us off.
Good luck!

It's not really an optical illusion - it just looks like one!
