Get manager experience.?

First off, you need a good educational background, then you must at least have a minimum five years experience in one particular field. Managers are experts and troubleshooters.

What I have describe to you are qualities and qualification of a Manager. If you have all of the above, then you can be a manager. However, these skills are learned overtime, Meaning you have to pass through different level of employment in a single field, which means you have to learn them through experience as these skills are not taught in schools, thought there are seminars on basics like planning, supervision, time management, financial management, basic accounting, etc. the proper usage and timing for these basics comes with practice and self discipline.

You can be promoted by your employer if you show the above described qualities. Future employers will only hire you if you can convince them that you have those qualities.

Good luck to your endeavor
