It’s already within you. Opening, or, open mindedness is the way. Self exploration & expression is the way. 
There is a psychological dualistic paradigm which sounds like ‘there is a process & understanding’, which I don’t have / know, and so I am lacking, and so I need to learn ‘how’ (need being related to identifying with the previous thoughts from which lack was derived). That ‘I don’t understand’ is an assumption founded on ‘that there is something to understand’. 
Make a dreamboard. Write everything & anything you want to do, be, have and experience in this life. Don’t ‘seriously contemplate it’, just add stuff whenever it pops up in thought / feeling. Let thoughts that don’t feel good to you go. Try this each morning, the earlier the better. The better you feel, the more that ‘pops up’. 
As days pass you’ll experience a vantage point that you have never experienced. You’ll see what you prefer, like, love, desire in a completely new way because it’s in front of you, and not swirling around in thoughts resulting in ‘lack’ etc. 
It is likely the mind is going to the absence of practical explanation...let that thinking go for now. One step at a time. Having millions of dollars is not as valuable as days filled with all that you love. And of course, there is a absolutely no reason you can not have your cake and eat it to. 
If I were to give you ten dollars for each dollar you gave me, you’d surely give me all the money you have. Such is letting a thought (the ‘dollar’) in discord with feeling go, and receiving ‘ten dollars’ (insights, passion, epiphanies, excitement, eagerness, jubilation, inspiration, etc). 
If the mind is occupied in the busy work of voluntary thinking, correcting lack, self improvement, etc, etc, etc...where can the insights arise?
Let go. Feel. Express. Watch it come together on your board - watch it ‘show up’ in your life.
