What do you do when you are tired after workday but need to do evening excersices? Where do you find the strength to complete routine?

Firstly I will relax myself by just standing in a open area where I find peace to calm myself. Then just 5 min self-talk (I am a very deciplined person) and I find strength in this only when I say that I am a very strong and active person, then I make efforts to make it. That’s how I complete my daily routine
