We have a few guiding views of readiness:
Skills and mindset are more important than gear.
The real troubles in your life are apt to be things that never crossed your worried mind; the kind that blindside you at 4:00 pm on some idle Tuesday.1
What you know and how you think will always be more important than gear you can buy. For better or worse, there are no shortcuts to the a survivor's mindset, and developing one is a lifelong journey. You rarely know what a problem will be, when it will occur, or what you'll have with you, but you can be confident that you will have your mind and body.
Your preparation should be custom to your needs
Every decision is a kind of prediction2
Every person and location will have different requirements. Before buying a kit of making a checklist, you should carefully consider the risks that you need to address, and how much you should be addressing them. Those risks will look very different for a family of four living in rural Alaska than a single 22 year old living in a Los Angeles apartment. If you decide to build a nuclear hardened bunker but don't have six months of savings, you are implicitly predicting that a nuclear incident is more likely than an interruption to your income.
Other people matter
Someone's decision not to be ready increases the chance that others in the area will suffer3
Our lives are intertwined with other humans. Your planning should reflect that. It is exceptionally unlikely that you will be in an emergency situation where nobody else matters - we have parents, siblings, children, friends, neighbors, colleagues, and responders to consider and care for. Be ready to help them, and above all don't add risk to them.
Something is better than nothing
Perfect is the enemy of the good You don't need (and probably shouldn't have) a survivalist bunker to be better prepared for disasters. If you're holding off action because it seems like to much - just do something! Risk won't wait, neither should you.
