Understand that it is normal to want to make things complex.
To want to add just one more feature. To want to make a clause for that particular case. To want to split the price to make it more flexible. To want to tell exactly how it works. To want to cover all the needs of all possible audiences. To want to factor in all the preferences of all possible stakeholders.
Understand that it is normal to want all of this.
And understand also that customers want simple. You yourself want simple when you are the customer.
Complexity is natural. It is also not what is going to make your business grow.
