No one is asking you to pretend that everything you have was done alone, but you must remember your very big part in it. Your consistency and the sacrifices you made should never be overlooked because if you ignore them, others will too.
Do not feel the need to pretend you got lucky just because someone else cannot see all the work you put in behind the scenes. You are allowed to say, “No. I actually worked really hard for this.” This is just a way to stop brushing aside your own effort without trying to prove anything. Acknowledge it for yourself first and others will start to see it too.
