If I am permitted to say a little more on these:

Knowledge:
Everything about life generally begins with a learning phase, so Bitcoin is not an exception. You have to understand the concept behind Bitcoin, how it operates, the trend it's currently at, and how you can swing it to your favour. I will also add that the process of acquiring knowledge about Bitcoin is a continuous one and not a one-time entity. I believe when you have learnt and acquired some Bitcoin with those knowledge, then securing it comes in.

Security:
You have to understand how to secure your wallet by securing your seed phrase and making sure third parties do not gain access. If someone has access to your wallet then you only have you to blame.

Patience:
You have to easily understand that Bitcoin is not MMM or CBEX that will promise you ROI in a few days, weeks, or months. You need to have that patience mindset. Bitcoin accumulation can take years according to your strategy and your target of accumulation.

Discipline:
Developing strategies that will make you consistent in your Bitcoin journey is highly important. It could be DCA or any other strategy, but being disciplined and keeping to that schedule is what will give you that edge in this journey of Bitcoin investment.
