If you are working towards a goal and trying to achieve something, feeling frustration is a natural part of the process.
The frustration of not being able to succeed in what you are doing (yet).
If you are frustrated, you are working towards flow and conscious of the fact that you are making mistakes and not quite where you want to be (yet). It can be a useful motivator, a challenge to overcome and it is very often that moments of frustration also can lead to moments of a high level of learning.
If we can perceive the process of frustration as a good thing and use ‘yet’ as a useful lever to move ourselves forward, we will reap the rewards.
