Personally, I have learnt that failure is a part of learning, growth and Success. You can also learn from other people's failures and use that as a stepping stone to your own success journey.
Remember, "You don't learn to walk by following rules. You learn by doing and falling over". - Richard Branson.
So don't stop trying, you might fail once but trust it's part of the process.
Let me hear from you too, what's your lessons?
