Your own knowledge is limited. By dealing with every issue alone you'll only ever be able see the things that exist within your limited personal prism. By yourself you ride the merry-go-round of your own experience, circling around the same options, the same objectives, the same obsessions.
But no matter where you're at in life, you're never alone. A million people have already gone through the same thing, or at least something somewhat similar. Use their lesson, learn from their experience, accept their help, take their advice. It may not be exactly what you need, but it can be a start. It can help you think differently, enough to send you down a new unexpected path, a path toward a better you.
