A key, to regain that feeling lies in deciding here and now, to do your very best to get the best from your current situation, no matter how you might feel right now.
Strife for thoughts which feel the most comfortable from those that are currently accessible to you.
If you repeat this whenever it becomes necessary, you will witness a great (!) improvement in your daily life.
This is how it is done !
In nature there are neither rewards nor punishments – there are consequences.
~ Robert Green Ingersoll
