Looking for answers

I've hit thirty already and what am I doing with my life?

Sounds like the start of a bad chick-lit novel. But it's true - I thought by now I'd have some of life's big milestones checked off. So let's see. Bought a house - no. Bought a car - no. Had a successful career - well, that's a work in progress. Fallen in love - no, but I was never really convinced that that was going to happen anyway.

So I've taken some time off work, a year in fact, and moved to London with the plan to travel. During this time, I'd really like to be able to do some soul-searching by the end of it. The big ticket questions that I'm looking for answers to are:
1. What is the meaning of (my) life?
2. What do I want to achieve during my life?
3. What do I want to be remembered for?

Sounds morbid, I know. I've felt so unsettled lately and indecisive always, and I think it is largely because I am so afraid of stuffing up, but I don't know what I want for the things that count.

Hoping to start blogging more, if nothing else than to draw the thoughts out of my head. Because I definitely don't feel comfortable talking about this with anyone else - blame the introvert in me.
