The hardest part of using mindfulness as your career development tool is committing to a practice. One way to overcome that is to use a tool called ASIA to plan when you'll do your practice.
Also know, that over time, the natural rewards of the practices make it easier to commit to.
Analyze: Consider the day to come, with the various activities you’ll be engaged in.
Strategize: Choose mindfulness strategies that might be appropriate for those activities.
Inspire/Implement: Make the intention to do mindfulness practices in life, and do them to the best of your ability.
Assess: At the end of the day look back at how you did with your practice in life.
I recommend looking at the week to come and planning when to do the formal practice. Choose a time each day for the formal practice and which technique you'll use.
You can also look at when you'll weave shorter micro hits into the day. Then each day review the plan, implement it, and assess it at the end of each day.
I have a simple calendar and in it, I simply write "m" when I meditate on a certain day. It might be something to add to your daily calendar or to-do list.
In the beginning, you might want to journal about what happened in the practice. If you can track and see subtle growth, you're more likely to stick with the practice.
If you miss a practice, assess why that happened and analyze what will work the next day.
