Having gone trough the ups and downs many many times really helps to put them in perspective and understand variance in how big of a sample is really needed to say anything. In that regard I truly don't care if things go up or down when I believe the betting itself was good.

Poor betting itself usually comes from some kind of emotional instabillity which can be a result of a random downswing, upswing followed by slacking, personal issues or problems, financial pressure.
Most of this can be prevented by understanding the mechanics and simply staying sharp. Eat healthy (plant based), work out, sleep enough, take supplements (Omega3-B12-D3), meditate,...

I hope this helps
