I actually have made several relatively big life decisions recently. "Big" in the sense that they've had a big impact on my life, if not in the long run. But since they have had big impacts on how I see things and how I interact with my world lately, I feel as though they'll count as big life decisions some time in the future.
The decisions were rather personal. Interestingly enough, they encompass almost my entire waking life. Friends, interests and school & work.
