You can only be yourself by being yourself. And that entails not deceiving yourself and trying to please people.
Well the best way to be yourself is to simply "be yourself". Don't try and change how you dress or behave because of someone else, feel comfortable in your own skin and do things in a way that pleases you, that's the best way to be yourself.
Don't change your accent because someone else is doing it, don't tuck in your shirt or wear a tie simply because others are doing it, just do you and you'll be just fine.
Being yourself can be difficult in this time and age especially since alot of people are walking, living, breathing copies of other people that they've seen on social media, but I tell you, the happiest people on the planet are the people who stick to the script that they wrote themselves, not the ones that they copied off a celebrity on Instagram or Twitter.
I hope this helps.
The best way to be yourself is to be real,don't live your life to impress anybody or pretending to be what you are not or whom you are not,the world is a free one,so live freely and be contented with whom you and what you have.
By remembering always who you are not.
This is simple but so many people has made it hard on themselves because they have been so fake that they forgot who they really are. No fake lives, don't derail yourself by doing what others do, stay focused, remember where you are coming from and where you would love to get to. All these would help you remain yourself
