And recharge by doing good, listening good, having prayers or being in nature.
Have an obsession.
yup you read correctly. Having goal is another thing but the obsession is that inner fire to achieve that goal and make it happen. Never live a day without planning what you wanna achieve out of it and make assessment at the end. It could be self improvement, some business or whatever just remain mindfully, happily busy achieving one. You may have a little break to rest or analyze something but a goal less life is painful.
Ask forgiveness from lord often. Astagfar is the best dua. And forgiveness just mean you free yourself and made your aura positive. Remember you are your own boss and you can make your own destiny.

Life is a path where different situations do come and you have to decide what you wanna get out of it.
