Could you also recommend a daily meditation routine?

I personally like early-morning meditations; the earlier, the better.
But I’d change the routine slowly.
Some strenuous exercise- running, weights, yoga, etc before meditating, as such activities will release a lot of energy, and energy always rises, this way helping you rise to higher chakras on your spiritual journey.
If you are seriously interested, read my book; I have dedicated a separate chapter to meditation alone, and I have also discussed the inner steps that you might encounter while traveling within, helping you identify them as they arise.
Good luck
More than routine, what makes meditation successful is enthusiasm, curiosity, and a sense of adventure.
There is only one source of happiness.
Whether you go within and synchronize with the bliss state or you run outside towards the objects of pleasure and find happiness, happiness is the same.
Happiness is the nature of consciousness, whether you connect with it by transcending the mind or you let the objects of pleasure temporarily make you forget the sufferings of your mind and make you mindless; it doesn’t matter.
Of course, one comes after running (for objects of pleasure), and the other comes by resting.
You choose.
