I'm a Software Engineer in my late 20s and just spent 2 years driving from Alaska to Argentina, purely because I wanted to. Along the way I continued to develop / create which helped supplement my bank account immensely. Keeping an up-to-date blog helped keep me focused and my head in the game. (theroadchoseme.com) I'm back working a desk job right now, to rest and recuperate and bolster the bank account enough until I can set off again.

If you want to do something like this, you totally can.
