Ah the phrase "I will try and find time to do xyz" how many times do you say it? I know I used to say it SO much it was crazy. Funny thing is I never found the time to do xyz and just like the word should the phrase "I will try to find time" became a pressure and unnecessary stress. Amazing how your words and inner thoughts can be causing stress just as much if not more than your outer world.
What I have become mindful of and I encourage you to try it too, is to catch yourself saying "I will try and find time" and change it to "I will make time for xyz". Going back to when we discussed being your own best friend and building that trust with your self, we will find this step links in with that. When you say "I will try and find time" you are already not trusting your ability to commit and follow through, which has an effect on your own self respect.
When you change it to "I will make time" You know you are committed and you will follow through. You will begin to only accept and take things on that you want to do, so you will begin to set good boundaries. You will build your inner trust with your inner best friend and you will build your self respect.
Give it a go and let me know how the next month goes. Remember it is a habit to say "I try and find time" so it will take a little while to re-wire the brain to say "I will make time". Be easy on yourself and make sure when you say you will make the time that you follow through so you are building your trust in yourself.
