Getting confused by various methods
Few suggestion I can give.


Don’t set the goal to get Jhana, No goal at all.
Don’t change the methods, Every methods was right it just a tool make you focus.
Do consistently. At least once a day and same time of the day.
Do anytime when you regcognize, Not just sit and shut your eyes.
Do when sleep until last moment you slept and do at very first moment you wakeup. This is an indicator that your meditation is progress. If you can continue the meditate from slept this indicate you are likely near Jhana.


Jhana is nothing special.
It's a state you can really control your concentration.

At initial step it's quite hard for people who are high skeptic or thoughtful with everything.

You don't need to take many hours everyday to sit and meditate.

You should try to take every seconds as meditate without distracting your work life.

Do until familiar then you reach Jhana.

Even it take 10 years still worth.
