Regardless of how talented or conscientious a leader you might be, it's inevitable that we all make mistakes. Yet, in a deeper analysis than what we might normally achieve, it appears that there are two kinds of mistakes.

The first might be what one normally thinks of as the definition of mistake: something you fail at, recognize, and never do again.

Read on for 7 mistakes leaders commonly make--so you're not guilty of committing them too.

1. Failing to delegate

One of the hardest things for leaders--especially leaders who are perfectionists--to do is to delegate their work to other people. Nobody can do it all alone, and the worst leaders are the ones who try.

2. Not communicating

When you provide adequate information to your employees, it empowers them to make substantial decisions that ultimately affect the shape and quality of the company. When they don't know enough, they aren't well informed enough to be able to make any decision at all.

3. Choosing the quick fix

While short-term solutions are definitely necessary from time to time, leaders who consistently pick quick patches rather than addressing long-term issues do nothing to improve the actual substance of the company.

4. Resisting change

The world's an incredibly dynamic place, and failing to stay up to date with change only sets you back. Be the innovation you want to see in your field--or at least keep up with what's happening right now.

5. Not setting goals with employees

When you don't know your employees' vision, how is it possible to determine what might be best for them? As a boss, it's your responsibility to know what your team cares about, so that you can do your best to make it happen while they give their best work, too.

6. Overlooking achievements

If someone succeeds as a project, it's right to reward him or her for their work, rather than attempting to sweep it under the rug. Acknowledging a big achievement is necessary--and boosts employee morale along the way.

7. Being too serious

Make your workplace somewhere people enjoy being--it'll make work more fun, for everyone.
