By taking responsibility for our lives we not only gain control of what happens, it also becomes natural to feel like you deserve more in life as your self-esteem builds and as you do the right thing more consistently. You feel better about yourself which is critically important because it’s most often you who’s blocking your own way and the way to success. It’s you who start to self-sabotage or hold yourself back in subtle or not so subtle ways, once you are on your way to the success you dream of.
To remove that inner resistance you must feel and think that you actually deserve what you want. You may be able to do a little about that by affirmations and other positive techniques. But the biggest impact by far comes from taking responsibility for yourself and your life by doing the right thing.
