Here are some of the tricks which will help you to motivate you to work:
• Find work that interests you.
Set your goals and work for them. Always work for what you love. You will love to work if you do what you love.
• Request feedback from your boss or colleague.
Work hard and ask for feedback. If it's good, then celebrate and reward yourself and if it's not good, then take it as a guideline and work hard for the next task.
• Learn a new skill.
This will help you to maximize your creativity and add a special presentation in your work.
• Ask for a raise.
Challenge yourself. If you are receiving the same type of tasks, then ask to raise the challenge. This will improve your skills with another level.
