I think consistency is a really useful quality to cultivate. Even a few minutes a day. I kid you not!
I honestly think 5 minutes a day will give more value than a single session of 30m a week. I like baby steps to build consistency. Most of the time I prefer to start slow, whether its in time or distance, reps etc and slowly but surely build up.
The first question I ask myself is how long, or what distance am I willing to do without any resistance?
It doesn't matter how small it is, the sole purpose is to eliminate all resistance and create a very doable starting point. Seriously, it can be a minute. There are no rules.
Next I slowly and surely increase the time or distance etc.
Whether I increase daily or every few days or weekly depends on what I'm doing and how I feel.
No rules. I say goodbye to "should" "ought" etc. The goal is steady improvement - there is no hurry.
I like pit stops or consolidation points. As an example, once I've hit a time, say 10m or 15m, I stay there for a few days or a week, whatever it takes. No pressure to move on. Once this time is consolidated I move on.
I was once taught "always make sure you want to practice tomorrow.
This is achieved by working within my limits. In Qigong a recommendation is use 80% effort, less if injured. No reason why I can't do this in life. No reason why I can't do this with baby steps. By practicing at 80% most of the time I will always want to practice tomorrow. If for some reason I start having some resistance, I can either go back to when I was happy to practice tomorrow or go back to one of my consolidation points.
Baby steps. Baby!
