You don't have to worship any deities, demons, angels or other entities for the sake of―well, whatever you have in mind; be it simple practice, self-development, spells, curses, healing e.g. Yes, you still should respect them, stay genuine and approach with clear intent, but worship is not something you must aim for.
An unpopular note I rarely see mentioned; most entities prefer not to be worshipped, at all.
Most worshipp is shallow and 'dry', they empty of any potency.
The benefit of a decent 'work connection' (or just bonding in general) with mutual respect and offering is not less than what a droid like worship with no genuine affection and dedication towards the entity itself could offer. In fact, it is often far less. The quality of your time, emotions, thoughts, energy and offerings towards them is real, and if you do 'worship' an entity for the results, you worship the results, and not the entity. Deities don't need this kind of approach, you won't fool them, and no one should fool themselves either.
The question is, do you want deities, demons, angels etc. by your side while you walk on the path of magic and if so, why? For you don't need entities to do that, at all. It can help, and it has multiple benefits, but nothing is impossible without them, either.
In fact, while I have almost two decades of practice with magic, the deitites, demons and entities around me are here for bonding (they called for me, I accepted), rather than pulling out 'anything fancy', and I spend most of my times with them; there's always someone (if not more) around me for decades, and I did not have them here for work at the first place, but because I love them. I did my magic 95% of my time without seeking for any help or suggestion from them.
Their presence, the process of bonding and the benefit coming from it helped me to improve without aiming for the result directly, and the pure genuinity is empowering this process, but, again, it is not necessary.
If you personally feel like that worshipping in a more formal manner would help your mind focus on the task, and allow you to slip into the right mindset and psychic stance, then go for it. It'll be profitable for your magic, mostly.
Just remember:
Just be honest.
Be clear.
Be willing to do the work.
and always show respect.
