I would like to add to what Fire has said, that in my experience, miracles totally can and do happen, once the lessons have been learned.
Once the planned lessons have been learned, the Higher Self is totally happy to make miracles possible. But again, that is AFTER the lesson has been learned and intergrated.
“Spiritual Masters” are usually people who are very good at manifesting “miracles” because they have learned most their intended lessons their soul wanted to learn, hence “higher positive forces” support them with “blessings”. This has nothing to do with any human religion, but that is the least esoteric way of how I can explain it here.
So the fastest way to manifest miracles in your life, is to proactively run towards the lessons that need to be learned and embrace learning them as quickly as possible.
Everyone usually knows what their next lesson is, if they are truly honest with themselves!
Furthermore, it is important to add, that the experience of human suffering is not necessary in 99% of the cases in order to learn those lessons. In most cases listening to your own inner wisdom, shutting up your own ego and being completely honest with yourself, is what allows you to know what and why you need to learn and to do next. Radical self-honesty is the key.
QL4, Alchemist Singularity, Love Bomb, Sage Immortal and RoS can help to understand certain things about yourself, which allows to learn lessons through self-reflection and also through observation of the external world.
Learning lessons through self-reflection and observation of things and of others is usually the rather pain-less way compared to learning through manifested experiences.
One cycle of each of these subs can already save a long way of having to learn stuff through external experiences.
Therefore, it is always recommended for people on a spiritual path to not wait for the lesson to manifest as an external experience through which it can be learned because that is not always pleasant, but instead, to learn the lesson through proactive self-reflection in advance. This approach saves a lot of pain in life.
