I don't know about you, but I'm sometimes pretty stubborn.
I keep thinking that I can do the same thing and create different results from it (like loosing weight).
If you want things to change for you, I mean really change for you, you have to create not only a new frame of mind, but also you have to embody what you want.
Old ways won't create and open new doors, it'll just give you plenty of unnecessary headaches.
If you're trying really hard to get somewhere or meet any goals and you're noticing that it's:
You need to at that point reevaluate what it is that you're doing. Have you really altered your train of thought? Have you changed your frame of mind? You can't get anywhere thinking you don't need to change or fix anything, and you certainly can't get anywhere using your old mentality to open new doors.
I know it can be challenging, if you've thought about something one way for a really long time to now having to change it, but that is what success is all about. You cannot allow yourself to stay stagnant in this ever changing world.
