Hey there,
I'm an aspiring philosopher and writer who blogs regularly. I'm about to embark on my first year of philosophy at uni. Thought I may as well introduce myself formally. I imagine I'll be most active in the philosophy sections but I could always scrub up on some theology stuff too...
I'm not sure what you could mean by going home that doesn't refer to suicide. But, IMO, suicide is perfectly fine and perhaps even logical for you. It doesn't have to carry the negative connotations it so commonly does. We shouldn't fear death but should be perfectly happy to go at any point...
Shouldn't one avoid ridicule, derision, criticism, embarrassment, etc. by ensuring they're well educated about that which they speak on? It's possible that, just by tackling particular topics, you will encounter criticism and ridicule (Sam Harris and Hitch' come to mind immediately).
Cheerful...
If your only agenda is modesty. Modesty is, of course, valued in intellectual circles. I don't think aiming low is a great general philosophy to have, however.
I don't think we could define it as "pure information". Pure data might be closer to the mark but I still think there's no benefit to thinking of the world in this manner.
