To really have a good belief in our selves we must change our thought process.
Most of us think in a way that was taught to us by our parents when we were young,
They learned from their parents & so on.
Very few people stop to think, about the way they think therefore repeating what their parents did & becoming like our parents even though we said we would never do that.
The key to changing is to pause for a moment & ask ourselves why do I react in a certain way to a situation. In this moment we can choose to take a different path rather than react without thinking.
