Why is a life with purpose (a synonym to "with aim") better than one without? The simple answer applies to your selfishness: because you'll be more confident in your dealings with others, you'll be calmer, and you'll sleep better. Knowing who you are and what you're really playing for gives you a perspective that puts you above the fray. It lets you pick your battles. It helps you make hard decisions (particularly with relationships). Indeed, it lets you see your day-to-day struggles inside the context of a much greater goal.
The drawback to larger purpose, of course, is that it's easy to lose patience with it. It's easy to lose your way - to forget your purpose, and to get drawn into the petty, pointless status contests that dominate most peoples' lives (note that you may need to take part on such contests, but when you understand them for what they are, games, then you can get better at and win.)
The reasons living your life with purpose are better than without are much like working on a software project with purpose vs without. The latter is difficult, almost impossible, and extremely painful. Purpose in the context of software should be defined by leadership, and it can be very arbitrary. But it must be there or you will flail and fail.
