One of the most important principles in life, especially when you are waisting your time with the wrong career. People often tend to be followers, after opportunities and destiny in life. I believe that it is not the ideal situation and by choosing the right position the objectives and preferences should be the leaders and not the other way around. It is also OK to make some mistakes but the important thing is to learn from it ASAP, become stronger and more importantly identify your goals in life.
Choosing your profession means choosing also the industry you are interested in. Being an expert, having a deep understanding and growing from there is a key success factor for enjoyable, self fulfilling career. Waiting too much with the right decision is also not recommended as comfortable is not playing on our side for the long run. Take an action, decide on the change and maximize your chance for happiness!
The change should come form the inside and sticking with this feeling is essential. You will need to remind yourself constantly that even though the journey for the right career is long and challenging it is the only option for happiness. Take a chance on your self, you deserve it!
