Keep your focus onthe road ahead. Many times the path may seem to stray, so make sure that you're walking on one ladden with footsteps. There are MANY before you who have walked this road, some only for a short period of time, but many have crossed it at least once. So don't think that you're alone. Or crazzy, as long as your goals are clear and you know where your going. You'll be fine, make sure yo have someone who know's your goals to check in with. Many times we think we're going up but we're in vertigo- we're going down. Or we think that we've completely fallen, but those steps backward help us to leap forward.
What ever happens don't give up!
