@Magic Qwan, unfortunately there is probably no true meaning to life. But imagine how awfully limited it would be if that were the case? Is it really worth it, to be tied down in such a manner? It is like when people would like immortality; the fantasy would be much more appealing than the reality.
There are two types of people - those that are able to live life on the very image that it presents itself as and nothing more. The other type looks underneath the scaffolding at some point or another to inevitably find out that it is seemingly being held up by void. No doubt that these people are prone to overanalysed and anxiety.
This second type often go one way or the other in life - to crumble and live in the meaningless existence that their minds have foreseen it to be. The second way is to live a fullfling and personally significant life. Thankfully we all have individual brains to think for ourselves and create our own reality. That being said, the simple answer is work.
When I say work, I'm not referring to menial labour - that is a one way trip to insanity for such people - what I mean is, following your passion. Don't let it just be a hobby; let it encompass you, become one with it. Being busy is the answer - stagnation is being dead when you are alive - and nothing is better than being busy, working on a passion. It becomes your meaning, and if you truly let it envelope you, you'll find that your worries just float away.
And with whatever it is, set goals for yourself and aim high. Don't settle for averageness. You can, if you want to, impact the world in a significant way. The proof of this possibility is there presence of many influential people that have come and contributed their work. Why not be one of those people?
I read that you enjoy writing. Well, there's your answer - that's the meaning you can apply to yourself. The contribution that you can give yourself and the world. I'm not saying that you shouldn't have anything as backup - that is always a must - but just don't let the writing, or whatever it is, take a back seat. Don't ever give it up; it needs to be cultivated.
A great shame is that many people do not ever find a passion, a deep one that is; sure there are hobbies, or some career path they had to choose - but nothing to such an extent that they become their field. People who succeed have two things; a passion to continue cultivating, ad the ability to fearlessly set high goals for themselves. Of course, many people simply do not care about such things - a family and a secure job are usually enough - and they're perfectly okay with that. They're the lucky ones really. If you are one of these people, then that is a very easy task to fulfil. I find though that these people are typically the first class that I mentioned, rather than the second.
I do think that trying to think objectively does nothing but create negative experiences. There's no point in this even, as we can never percieve full objectivity anyway (I admit to trying to do so regardless, and it never leads to anything satisfying or absolute). But preoccupying yourself with what you enjoy the best is the answer. Keep at that and it will simply not be capable of doing anything else but continuing to grow.
