Dear Zoe,
The "blockage" is within your own self. There is a "fighting-to-combine' structure in your BaZi Chart. This causes a lot of confusion and instability in that person's thinking.
Your opportunities will come as you as you can find CLARITY within yourself.
To do this - first - learn to let go of the past. Dun hang on to things that are no longer important. Seek out what your gifts are (if you don't know them by now, this could be the main reason why you fail) and start giving them.
Your personality is your asset.
Cheers, JY
