what should I do to feel good about myself? 42.1> 20

As you know from my previous castings, I have a relationship or something similar a relationship, that doesn't feel me totally comfortable.
I think the most important thing, in this moment, is feeling good about myself, before I can be comfortable with anyone else.
so I asked: what should I do to feel good about myself?
Answer: 42.1> 20
Wilhelm_Translation: "Nine at the beginning means:It furthers one to accomplish great deeds. Supreme good fortune. No blame. If great help comes to a man from on high, this increased strength must be used to achieve something great for which he might otherwise never have found energy, or readiness to take responsibility. Great good fortune is produced by selflessness, and in bringing about great good fortune, he remains free of reproach."
Here ... I didn't understand anything ...
Selflessness? I need to assert myself now and don't to be selflessness. One of my bigger problems is that I can't say no, when someone ask me something, expecially at the beginning in love affair and with people that I don't know very well.
And 20 contemplation...I'm attending a Sahaja Yoga group (not consistently), is it the right direction?
