You decide to wake up at 6am in the morning.
You set an alarm of 5:50am.
The alarm start buzzing and your sub-conscious mind comes into play, it says:
“Dude! It’s just 5:50am bro, our waking time is 8am.So let’s continue sleeping.”
This happens due to the habit pattern in our brain. So, to break it we must work consciously on it unless and until our sub-conscious mind understand this pattern. After that our mind only start helping us.
Here the only secret is you should put some serious constant efforts every day. Rest will happen on it’s own and you will be surprised every single time.
