I'm currently studying Psychology and picking up ANY kind of work I'm able to find. I'm also helping my parents and my partner. Sometimes I was overwhelmed by this, and found that "practice" was impossible. I tried sticking to a group meditation session (for consistency) but my shifting schedules made it so hard that I ended up having to drop out because there was no way. Even my daily practice was being interrupted.
In Spanish, we have a saying: "Quién quiere, puede" "If you want it, you get it". That's the motivation! What's behind the motivation? Wholesomeness, compassion, and hard-work! That last bit is what I forget sometimes in the path. It is hard-work, it is re-wiring your brain, ordering your mind; like cleaning a huge basement. It is not about getting it all cleared -which would be great- but maintaining certain consistencu and also learning how not to clutter up and return to the previous unwholesome / chaotic State.
For my case, I learnt I simply had to go to bed early, wake up earlier. I found quite inspirational this ex-marine called Jocko Wilkins. I know it might not sound very Buddhist / compassionate, but I take his discipline and the physical exercise routine as great aids to my path.
Good day to you all!
