Set a time and do them. Notice how much better you feel and how much more empowered you are. You needn't even clear any beliefs or stuck emotions around these important actions. You can clear after you take action if you still need to do this work. Fear of rejection can be cleared after you've taken action.
Action tends to burn out fears of rejection over time.
If you have a pattern of stuckness, the beliefs and emotions involved in this stuckness may be cleared to make sailing easier in the future. Still all we need to do is to get up and do the required action. We can chose doing over giving our attention to feelings. Those feelings change when we take required action. Never wait for inspiration, the right moment, or motivation.
