Everyone wants to be happy, but not everyone is actually committed in doing what it takes to become happy. A real and honest commitment with yourself requires that you master the proper attitudes and actions to create happiness. Of course it involves careful study and practice. When you want to make a commitment simply saying you will do it will not suffice. If you want to learn to ride a bike the first step is to buy a bike. Imagine someone claims that it is important for him to learn to ride a bike but when you ask him if he bought a bike he says no. It shows that the person is not serious about learning how to ride a bike.
Just like making a commitment to learn how to ride a bike is up to the person, so to happiness. A person's commitment to trying to master happiness is all up to you. You can create it or destroy it all in a matter of moments if you choose not to apply happiness to your life. Your intense commitment to master happiness will enable you to experience more happiness for yourself and for the many people that surround you. They will be able to benefit from your happiness and they will be able to benefit from the way to interact from a place of joy. Even if you feel you don't deserve to be happy, or you feel that your life is too damaged to be happy you need to remind yourself that you were born and therefor you have an automatic birthright to happiness. You don't need to be considered special by any other person to have a right to be happy.
Every human has intrinsic worth and infinite value. When you know and feel that you have a right to be happy a potential barrier or blockade to your happiness is automatically removed. People often make the mistake that happiness is only for those people who deserve it or those who have a right to be happy. However there is a huge flaw with that logic. Who created the criteria for people who are deserving or not deserving of happiness? In reality, all it is, is realizing that the ability to be happy stems from yourself and that it is your birthright.
The decision is totally up to you to be happy, and you should make it your obligation to get to the root and master your happiness.
