You are going to be successful in creating the life of your dreams. You have to believe that you are capable of making it happen. You have to believe that you have the right stuff and that you are able to pull it off and weather you call it self esteem self confidence or self assurance. It's a deep sea to believe that you have what it takes, the abilities and resources the talents and and skills to create your desired results. Now believing in yourself is simply an attitude. Believing yourself is a choice. You have to choose to believe that you can do anything you set your mind to, anything at all because in fact you Can.
The conversation that stops you from doing the things you want to do less, don't do that.
The next thing that is a key to self motivation is you have got to ask yourself
what do I want out of life.
What do I want out of a job
what do you want out of career
what do you want out of a relationship
what do you want what gives you your life. How would you know when you got it what will make you happy.
You need to start asking yourself some questions. what do I really really truly want. Your need to be exact about that don't be vague , oh I just want to be happy that's to evade what will make you happy.
How will you know when you got it. Zero in on it, be exact, be specific and as you do that that will stimulate that superconscious mind or reticular activating system of your mind that will begin to find those things to identify.
