If we intend to develop ourselves personally is because we are pursuing the success of our goals, however many of these goals are impossible to achieve without being prepared for the possible inconveniences that may arise in the way of achieving these successes.
We cannot leave aside the use of emotional intelligence to achieve personal development in the fulfillment of our goals, because when we apply emotional intelligence we are developing the ability to control our emotions and manage them in favor of our achievements.
If we were to talk about keys to achieve personal development it is important that we at least have clear the application of many of them, for example we can enjoy our loneliness, this means not to see loneliness as an enemy, but take advantage when we have it to delve into some aspects such as being able to delve into our emotions, feelings, desires, and generally explore within ourselves and draw conclusions about why we act in certain ways to our environment.
Any strategy that we find that is motivating for us and for our personal development is valid, there is no need to copy models that tell us what we can do to develop ourselves, however a set of rules that are written in conjunction with some of our own, surely it can mean the perfect cocktail to be applied in our lives and go personally develop based on the fulfillment of our goals.
For me, it's the goal of achieving success. If I want to live a comfortable life, and life not worrying about anything, I should always work hard for it.
