Quarter life crisis: Advice? 
Hello.

[LongSelfIntrospectionRantAlert]

I'm in my early 20s, out of college for 1 year now with a degree that decrees me as an engineer. Although I've pulled through the better part of my academics with decent grades, I've been fighting what seems to be a losing war with mediocrity. At this time, I'm facing a severe motivational crisis to do any fscking thing in life.

In no particular order, the below mentioned points describe my current state of mind and work:

a) I hold a long standing consulting career as a developer. I got sucked into this at some point during college. While the money is reasonable (for where I live), the work itself is normally pretty uninspiring.

b) I have a modest amount of contributions in f/oss-land. I wish to do more, but frequently turned off by how all the projects I'm related to work.

c) I fiddle with a couple of ideas -- mostly forks of f/oss projects. Juggling as many things as I am, and being a one man army, there's very little of achieving much. At this point, I've also given up on approaching b-people for funding or fellow geeks into collaborating. I'm also considering giving up altogether.

d) Outside the tech-zone, I "partner" a small travel-related startup. This was showing hope at one time, but now it's probably at the end of it's lease.

e) I'm also at a low as far as personal life goes. The last breakup happened more than an year back now. I'll admit that I'm emotionally, sexually frustrated. Being compulsively prudish hasn't helped me find the short term solution either.

f)I also suffer from chronic wanderlust. This is one of the reasons I've been keen on being all by myself. I've come to understand that this is important for my sanity.

Currently, my life revolves around my folks, code, IRC, HN, reddit, coffee, lemon tea and travel. Being mostly shy and introverted, My behavior these days is quasi-sociophobic.

Back on the topic, I've tried to identify a few options for the way forward. Please feel free to suggest more:

a) Push for a post-grad in some US-varsity: Although I can bet on the GRE, I'm neither technically (albeit for some reasonable programming ability) strong nor inclined to academics anymore. Besides, exiling from my hometown doesn't sound like a great proposition.

b)Drown in the ocean: I've penetrated openings in big companies in campus selections at college. It won't be hard to be there again. I will probably have to bear some backtracking in terms of income.

c) Management:
I was inspired by the amount of credence MBAs from good B-schools tended to get at various startup / entrepreneurship events I've been to. I'm also told that a tech background + MBA is a killer combo.

I've thought that this would be the best fix for making peace with the depression caused by mediocrity and under-achievement this far.

The catch 22 is that competition for B-school entrances here is rather high. Realistically (with my motivational issues as of now), I don't see myself making the cut. I wouldn't want to settle for yet another mediocre school.

d) Inertia:
Empty catch. Just hope I get lucky.

Any life-changing, inspiring advice from HN'ers would be appreciated. Please recount similar experiences if any.
