Is attaining to Jhana possible for me?

I searched for the word 'Jhana' on this site and read almost all about 50 odd questions on Jhana. I asked few questions myself. It seems like one has to put extreme efforts to attain to Jhana. This is part of one of the answers; > ...They sit 12+ hours everyday for many months or years to get this light > which can shine in their mind trough the dark night. It is shining > breathe or meditation's object, not sunlight. Today, many of them have > not been laying on a bed for 20 years... This isn't practical for lay disciples, or at least for me outside of retreat. At this point Jhana feels like a wishful thinking. Should one aim for Jhana in sitting? If not Jhana, then, is there any other state to aim as an intermediary to Nirvana. I do a daily 90 minute sitting and some chanting. Is it possible for me to attain Jhana? What is recommended daily duration?
