you'll know the time to change when your current life feels so empty. don't listen to people who says you don't need to change because you are what you are. they are being sellfish. they are comfortable with how you are now and don't want you to change for their benefits. you change when you feel you need to. not because of what people think and told. you know yourself better. so if someone don't like your changes then you just need better companies.care for your own feelings 1st before others...ohh this is not an advice. this is a monologue.
