This is primarily a metaphor which means that you can be a lonely lion, but that’s absolutely fine. A lion might be lonely, but he still remains the king of the jungle which simply means that even if you are not in a flock, you still happen to be the king and win it.
It is rather good to be the winner than to think about being a sheep who moves around in a herd but has no such significance as an individual.
All you need is to be different and unique from others to make sure that you have a different place for yourself. Your existence might seem to be lonely for you, but it would not actually matter if you are good enough, and is simply an expert in your own field.
A lion might not have a team accompanying him all the time, but he is still the king, and his position in the jungle is in a much more dignified place than any other animal.
On the contrary, a sheep might move in a herd, but no one knows a sheep individually, which simply signifies the reality of the human race. All of us prefer to do things that all the rest of the people around us are doing.
We hardly bother about standing separately and trying to be unique and innovative. We are so much into following the trend that we hardly have a desire to be the change-maker.
This, when related to life, simply means that you should not just follow the herd of cattle. Rather, you should focus on doing things that make you unique and different from the rest of the crowd.
It is absolutely fine even if that makes you aloof from the people around you, but at least you will be able to set a different identity for yourself.
