Setting goals and focusing on them
Ensure your goals are clear, preferably measurable, and move towards them every single day.
Being interested in others
Listen to the people around you and talk to them in such a way that they feel special. Praise subordinates and include them in decision making processes.
Working 100%
When solving tasks, use all the available tools and resources, and never leave anything unfinished.
Initiative
A good leader is an inspiration to others: they do not go with the flow, they are not afraid to step out of line, take the initiative and come up with new, unexpected solutions.
Engaging others
Do not hesitate to include subordinates in decision making processes and important projects. By working with team members and treating them as equals, you show you trust their skills.
Do not expect recognition
Never do anything just because you expect to receive a reward or credit for it. Do things that need doing even if they are not your responsibility and without asking what you will get in return.
Being a role model
Never do things you would not like coming from team members and other colleagues. Stick to your own moral code.
Taking responsibility
Do not avoid responsibility. Do not make excuses and blame subordinates or certain negative circumstances; instead, always accept responsibility for yourself and your team.
Respecting other people's schedules
Do not waste other people's time just as you would not waste your own.
Believing in oneself
Successful leadership starts in your head. If you do not believe you will be successful, you can never become so in the real world.
Trustworthiness
Do not equivocate, do not hide behind vague expressions, and always deal with people openly.
Stress management
Stress should be a driving force, not an obstacle. Learn to handle your stress levels and do not let stress overwhelm you.
