There is an old saying, 'If things are going well, steel yourself. Sooner or later, they're going to get worse. If things are going badly, cheer up. They will improve, even if all you do is wait.' A very natural law dictates that sooner or later, everything must change. If,  you want the fun to last longer and the stress to pass faster you must identify less closely with narrow definitions of success and failure. Stand back to see your situation for what it is, not what you think it is. 
Lovely though some of your friends are, you can't always rely on them for support. It's not fair to say certain people are letting you down at the moment. Some may be, but others are doing all within their power to help. It's just that their powers are limited. In September, your power to help yourself, however, is much greater than you realise. No matter what you find worrying, be brave this month. You will find, as soon as you determine to press ahead alone with a positive plan, that you have company of the most inspiring kind. 
 Imagination is actually a very practical thing. So too is self-indulgence. And there is a very real point and purpose to a certain amount of time-wasting. Truly practical people appreciate the importance of inefficiency. When you try too hard to make every second count, or every penny... you raise an impossible expectation. There's nothing practical about that. Try to focus too hard  and you'll make the edges even more blurred. Approach goal at a steady pace and you'll soon find you are practically there. 
  People talk about 'the devil you know' and 'the devil you don't know'. The whole trouble with devils, though, is that we don't ever really know them. They are full of surprises. The moment they start acting predictably is the moment we can formulate a strategy to get the better of them. Anyway, you do not have to make such a choice. You can have both devils! You can also have some wonderful friends, old and new - as long as you don't start inadvertently demonising anyone or anything!
