Happy birthday and welcome to 31, its fab!
I remember when I was about to turn 30 and I was panicking a bit as I hadnt done half the things I had wanted to do before "getting old" (ah the naivity of my 20's
) and I asked a friend of mine who was 36 what it was like, she told me 30's are the best as you can still do all the things you done in your 20's but are a little wiser and able to think about consequences, plus most people are pretty settled by then so have more mental energy to commit to personal persuits.
Im 31 too and loving it so far!!!
