Holding onto Sabr and Faith in Our Duas

Assalamu alaikum, I’ve been praying and working hard towards this personal dream for a while now, but honestly, I haven’t seen any big changes yet-just some tough patches and delays. I really, really want this to happen, more than anything else. I’ve been making dua, even asked family to pray for me too, and I’ve tried waking up for Tahajjud several times... but still no clear sign. How do I keep trusting Allah will answer if I’m putting in the effort? And how can I shake off the doubt that maybe my prayers haven’t been accepted yet?
