Even before achieving something,
- If you feel you are not enough
- If you feel you do not deserve it
- if you see only your limitations
- If you analyze how you would fail instead of how you would overcome the challenges
Then you are preparing for failure and you would give up in the middle.
If you feel you are not good enough you will pull yourself to the same level that you believe in and comfortable in. If you feel you do not have what it takes and feel you do not deserve great things in life, you will unconsciously drag yourself to lower standard which you are not happy about in the first place.
